20DD300N3EYNBCNNN

The 20DD300N3EYNBCNNN model by Allen-Bradley is classified as an adjustable frequency AC drive, falling within the PowerFlex 700S series. This device is tailored for three-phase systems, operating efficiently at a voltage rating of 480V AC. It can sustain a normal-duty current of up to 300 amps, making it ideal for high-demand applications.

This drive offers protection in typical indoor environments. Its enclosure is rated IP20 and compliant with NEMA Type 1 standards. For user interaction, it includes a full numeric LCD display, which simplifies monitoring and setting adjustment.

In terms of performance and reliability, the unit features an IGBT braking system, which enhances dynamic performance during operation. Additionally, it is equipped with an adjustable bus undervoltage trip function, allowing users to set specific thresholds based on their operational needs. The integrated heat sink thermistor ensures that the drive operates within safe thermal limits, as it is continuously monitored by an embedded microprocessor that can trigger an overtemperature trip if necessary.

Operational stability is further bolstered by the logic control ride-thru capability, which allows the drive to maintain its settings for 0.25 seconds while not actively running. Additionally, the power ride-thru can sustain the drive for 15 milliseconds under full load conditions during temporary power disturbances, ensuring resilience in fluctuating environments.
